Lionel Super O NO.37 Uncoupling Track Set in Original Box with paperwork

Here is the complete set in original box in very good condition. What a find. I not sure but in this condition I would think it would be considered rare find and I hate using the word Rare as seems a lot use it so freely its sicking as when you do have something rare who believes it. Now finding all of this probably not hard but all together and with a box in the condition this one is in even harder. Nice collectible piece. Any Questions please ask before bidding. Will combine when possible. Thanks for looking please check out my other auctions as have a lot more to add over next few days.
